While it's awesome that banned users cannot chat, there is a major safety issue in them still being able to view the stream.
When accounts are banned, they should not be able to see the stream at all. This is dangerous because stalkers can still view streamers. Many streamers agree that when an account is banned, they don't want them to have ANY ability to interact with their stream, even if it's just viewing it. Banned should mean banned from all.
Also giving mod tools to confirm a raid when it's someone we don't know so we can see what's going on or more protection when hate raids happen?
